"imrposes as 'erating handle 28. This operatin handle carries slotted spanner arms 29 W ioh'project on 'either' side f'the'shat 21' and' receive pins 30- on a'elnt'ch'collar 31.y This driven by a' sprocket. wheel 3.7 from any salta-(ble source of power. As the sprocket f Wheel 3,4 iis spl-ined to the. shaft it is pos- .sible to move the carriage formed-.by the Column 8 and bearings 9, and. rollers 11; to either end ofI the base plate 1, and thus present either pair of rim carrying rollers to the operafzol'-, and to the conveyor on which the hard bases are supplied, as will be described.

,Qn the upper part of the column Sthere are formed rearwardly extending brackets 38 inthe outer ends of which is 'mounted a horizontal shalt 39 which carries secondary rimsupporting rollers 40,. These .rollers are arranged to be .driven trom sprocket wheels 4l secured on the outer ends or the primary rim supporting rollers. Sprocket chains 42 pass over the sprocket wheels 4.51 and over sprocket wheels 43 secured on the secondary rim supporting rollers. Brackets 4 may be secured to the column 8 at either side and are arranged to carry chain guards 4o, las shown in Fig. 3.

The rim 46. is placed over the rollers 22 and $0. on one side of the machine. rEhe hand lever 7 is now operated to bring the on-the rear side ofthe columns.

carriage in line with the conveyor 47 which brings a strip or hard rubber compound from the eX-truding machine and on which conveyorA the -strip may be cut to the exact length required to go around the rim. A portionol'the rim in Fig. 1 is broken away and shows the hard base 48 applied thereon. In order to press the hard base into intimate contact with the rim, there are provided pressure rollers adapted to be positioned over the rim. These rollers are. carried by a slide plate 49 mounted for vertical adjustment in av guideway 50. formed A .n A hand wheel 51 operating in a slot '52 o" the column is provided for the pur )ose of securmg the slide in its vertical a justrnent. A screw` 53 assin' through a lu' 54 on the ront of t e sli 'e 49. bears against the upper end of the column 8 and furnishes a means for moving the slide vertically. The slide 4.9 carries ahorizontal shaft 5e which extends over the rim supporting rollers. @n the enter ends of the shaft S'are mounted sleeves o5 each of which carries a stitcher roll'supportin yoke 56 in the outer end of which is'c'arried a Win57 on'whicli is mount edthe stitcher 58;*"Th'i's'stitcher is in the form of a roller and is slightly corrugated in order to fol'ee'-tlie rubber more intimately into contact with the grooves which are usually formed iu the rim, The stitcher rollers` may be changed when ditierent sized rims are operated upon to enable a certain range of zuljustability, but if further adjustabil-ity is desired a second set oij dllerent sized yokes with diliGrent sized stitch ing rollers may be provided in place of those shown. The sleeve 55 is formed with a handle 59 on which ,the operator may press, forcing the roller 5S down upon a hard base as it is applied to the rim. A notch (30 is formed on a collar 6l located on theslidefi 49 the notch being adapted to be engaged by a slidable detent 32 mounted in a box ing 63 on the inne-r end oi the handle 59.. This. detent .serves to hold the st itching .roller 58 upwardly out of Contact with the rim as shown in dotted lines in Eig. 5. A ull bar- Gll 1s mol-.inted along the handle 5.9 eing urged inwardly by a spring G5, the

Ioperator moving the pull bar outwardly when desiring to manipulate the stitching roller 58.

On'the trout face of the supporting column 8 there is ormed a vertical guidcway 66' on which is slidably mounted a carriage 6.7. This carriage (37. is hollowed out to form a semi-circular recess 68 which is covered by a plate G9 having a semi-circular `recess similarly formed. Rotatably mounted' at each side of the casing rmed by the parts 6.7 and G9 is a supporting spool 70 formed with enlarged portions inwardly and outwardly of the casing, it being held in place by a cap 69. The outwardly extending portion 7l of the supporting spool at each side of the casing carries two parallel rods 72 which are united at their outer ends by arms 73 provided With handles 74. Slidably mounted on each pair of rods 72 are a pair of guiding fingers 75 having screw threaded engagement with a centrally located reversely screw-tlnemled shaft Z6 operable by a hand wheel 77. rThe Whole oarriagc `formed by the parts 67 and 69 and tho outwardly extending rod is movable vertically in the guideway 66 by a vertical screw 78 mounted in a step hearing 79 at the lower part ol the column and extending through a bearing 80 in the. upper cud thereof. A hand wheel 8l furnishes means 'for rotating the shaft which communicates vertical movement to a boxing S2 at the back ot the slide 67.

It will be 'seen that by operation of' the 'hand wheel 8l the guidingiingers 75 may be moved vertically to accommodate rims oi dilierent diameters as they are hung on the supporting rollers, While by manipulation ol f the hand Wheel 77 the lingers may be moved to contact the sides of the rims of' different widths. The handle 74: may be used 'to rock the guide linger supports about in the cas ing 67'and 69 so that the guide fingers may be removed from the side of the rim when it is desired to taire the same from the machine.l

lt is believed thatthe operation of the machine *willl have been understood as the description proceeded.

llt is obvious that changes may be made in the invention Without departing from'the spirit of the same orsacriticing any of its benefits.
